GALVANIC BATTERY.

Specification of Letters Patent.

Patented Dec. 31, 1912.

Application filed February 19, 1912. Serial No. 678,808.

To all whom it may concern:

. Be it known thatI, EBEN G. Donor, a citizen of the United States, anda resident of South Orange, in the county. of Essex and State of New.Jersey, have invented certain new and useful Improvements in GalvanicBatteries, of which the following is a specilarge quantity effects. Theinvention however is not limited ,to connecting up the various elementsin parallel relation.

The invention is particularly useful for that class of batteries inwhich one of the elements is c'omposed of a mass of copper or other oxidor depolarizing agentheld in a metallic support.

The invention will be described and carried out in a battery having forone element copper oxid and a copper sustaining frame, and for its otherelement a plate of zinc.

The particular features of construction constituting my invention willbe first described in connection with the accompanying drawings and thenspecified in the claims,

Figure l is a side elevation of a battery constructed in accordance withmy invention, one of the plates constituting the zinc element beingshown broken away, as well as parts 'of the sustaining frame for thecopper oxid. Fig. 2 is an edge view of the same, partsbeing shown insection. Fig. .3 is a horizontal cross-section on the line aa Fig. 1.-Fig. 4 is a horizontal cross-section showing a modification in the formof the grooved or channeled bars constituting a part of the sustainingframe. Fig. 5 is a front elevation of a modification of the battery,Fig. 6 an edge view, parts being shown in both cases broken away. Fig. 7is a horizontal cross-section on the line 7-7 of Fig. 5. Fig. 8 shows aperspective in the manner of connecting the zinc plates with a commonelectrical connecting bar. Fig. 9 is a side view of said bar showingsome of the ears of the zinc plates turned down on the top of said barpreparatory to welding or soldering. I

1 indicates a metallic yoke preferably.of copper having a. screw or boltextending upwardly at the center to afiord means for hanging saidyokefrom a suit-able support over the battery containing cell containing thesolution. The depending ends of said yoke carry the vertical channelbars 3 of copper or other suitable metal which constitute the verticaledges of a metal frame or frames carrying the copper or other oxidtablets 4. l

In the present instance I show two frames in which are assembled copperoxid tablets or plates 4 to form two negative plates for the battery.Intermediate the bars 3 forming the edges of the-sustaining frame areother sets of bars 3, all being assembled to form a frame sub-dividedvertically, so that in each negative plate there shall be four verticalrows of oxld tablets. Obviously, the subdivision might be carried to anydesired extent. In the Figs. 5 and 7 the sub-division'is such as toafford eight vertical rows of tablets.

At or about the center of each sub-divided frame the spacing block 5 ofinsulatin material is provided at the top of the ame and. a similar one,at the bottom indicated.

at 5'. Obviously, any number of spacing blocks might be used. Throughthese spacing blocks extend the horizontal bolts 6 which tie the channelbars constituting the frame together and to the yoke 1 at the top andbottom of the frame, as clearly shown in the drawing. L

The grooved or channeled bars are preferably so formed as to have arocking bearin at the points where they bear and are force against thespacing blocks, and also if, desired, where they bear against oneanother back to back on the lines of the vertical subdivision, thepurpose of this being to accommodate any irre ularities of the tabletsand to prevent brea age when the tie-bolts 6 are drawn up. Intermediatehorizontal bolts may be employed, as shown, at or about the center, tofurther stiffen the frame, the effect being also to form a furthersub-division of the frame, which is however not important. As will beseen, the tablets constituting the upper portion of'each negativeelement are sustained upon these intermediate horizontal -6 sustains thelower set of tablets. This construction of frame permits, as will beseen further, sub-division of each negative element into a large numberof copper oxid plates'which in effect are mere tablets and which, beingof small dimensions, are much less liable to breakage than the largersize of copper oxid plates heretofore employed.

The zinc or positive element of the battery consists of zinc plates 8alternating with the copper oxid plates and sustained from the sameframe as the copper oxid element by attachment to the spacing blocks 5of insulating material. This attachment may be effected by means ofbolts 9 passing transversely through said spacing bars or at rightangles to the rods or bolts 6. Intermediate zinc plate 8 is held betweenthe two sub-divisions of spacing block 5, as clearly indicated in Fig.3. The zinc plates are preferably provided'with the upwardly extendingears 8 through which the fastening bolts or rods9 may be passed. Inorder that the zinc plates may be joined together as one elementelectrically, the upper ends of said ears of whatever form, are passedthrough slots in a connecting bar 10, as shown more clearly in Figs. 8and 9, and the ends of said ears are turned down upon said connectingbar and are then welded by the oxy-acetylene flame, or otherwiseconnected to said bar to form good electrical connection therewith, saidbar thus becoming the common terminal of the multiple zinc plates. Thespacing of the zinc plates from the oxid plates at the bottom is insuredby the subdivided spacing blocks 5 at the bottom of the frame, asclearly shown. v

. In the modification of my invention shown in Fig. 5, the yoke 1,instead of having its ends bent down to connection with the channel barsforming the edge of the frame, is made straight, and the end bars aswell as some of the intermediate bars of said frame are attached to saidyoke in the manner indicated in. Fig. 5. In this form of my inventionthe sub-division of the copper oxid plates to form a verticalsub-division devoid of active material, which is the efi'ect of theconstruction shown in Fig. 1, is produced by the useof vertical spacingrods or bars 5 extending vertically from top to bottom of the frame, inwhich case the transverse bolts like 9 and passing through the zincplates may be repeated as often as desired to secure the desiredrigidity and fixity of position of the zinc elements with relation tothe copper oxidplates or elements facing them. In both constructions, towit those shown in Figs. 1 and 5, it will be seen that there is asub-division of the metallic framework vertically making it possible tosub-divide the copper oxid into small tablets which are slipped into thevertical sub-divisions and held in position in the channeled members ofmislead the sub-divided frame. It will further be seen that thesub-division at or about the' center of said frame to afford a space inthe ing of that portion of the zinc element, and

said portion will form a sustaining rib which will be unimpaired by thebattery action and will afford by a part projectinguxpward therefrom outof the battery liquid "a. support for the disintegrating portions of theplate, so that the latter will be more completely consumed beforefalling apart.

What I claim as my invention is: 1. A voltaio battery having a negativeelement consisting of a framework comprising a series of channel bars ofconducting material arranged and spaced apart vertically with theirchannels opposed to one another to afiord a series of vertical tabletholding spaces and copper oxid subdivided both vertically andhorizontally into a multiplicity of tablets "and sustained? in thespaces between said bars.
